I remove them from the car and wet sand them first with 400 grit sandpaper keeping the headlight wet then I move up to the 600 grit . During the sanding process you will want to change directions to try to keep from making low spots. Then 1200 then finally 2000 grit. On the last sanding you want to go horizontal to try to Deter runs. Now wash the headlight down multiple times with rubbing alcohol and paper towel while the headlight is wet with alcohol you can look into the plastic to see what it will end up looking like once it’s clear coated. 2K clear coat

is what you want to use going on eBay at $20 a can. It has a Hardner in it that must be activated before use. It is supposed to be used up within 48 hours of activation. My experience with it is you’re lucky to get that time before spray turns crappy and no longer layers on the surface correctly so I try to use it up when I open it.

One can will do five or six pairs of headlights. That’s with giving them three coats. You want them to be wet coats but not heavy. If you do happen to get a run in it, you’re better off to let it dry for a week before wet sanding and buffing it. This is the after shot of the same headlight in the first picture.

They can be wet sanded with 3000 grit and then polished but I was happy with how they looked after spraying.
